This is a compact version of my previous spiked ribbon. Using the bowl from a board method I used the 8 spiked star template (pic 6) to cut 2 half bowls and 10 quarter bowls consisting of 4 layer 1/2” thick at a 45 degree angle.
I used a no 7 scroll saw blade and had minimal burning on the 40 points. Cut from 1/2 thick plywood I cut the sections on the narrow edge of the star and the completed ribbon is roughly 13 X 13 inches. Gluing up is the most
tedious as the sections cannot be clamped but in the hot weather here at the moment the Titebond cures quickly.

Getting the 90 degree angle on the quarter sections is the key the successful meet up of the final sections. The first cut is the is made the same thickness of the ply hence the 45 degree cutting angle and then mark down using the previous layer. The base is not used. After gluing the layers of the section together this is the time to do the majority of the sanding.

As far as I know I am the only person the produce one of these on the scroll saw. Glad to answer questions and if I ever do another I will do a blog with photos of progress.

These things mystify me, Bob. I’m reminded, as I view it, of a flock of iridescent birds I once observed, in Florida, going berserk over a pile of popcorn in a parking lot. That’s what I see. It’s a thing of wonder and beauty.

Hey Bob, you got way too much time on your hands Mate.
Looks like you need to get a job. LOL.
Kidding aside, this is truly mind blowing, you are a sucker for punishment, and a great Craftsman.
Thanks for sharing.

Bob.

another one beyond my imagination. Takes someone special to “see” these things before they’re made. Nicely done, and thanks for sharing.

Bob, the möbius from curved bowl parts could not be clamped, as there was nothing flat. I’ll just have to cut one of these myself to see why this variation cannot be clamped at the glue joints…I’m thinking that it can. (Tibbetts used a method of clamping his curved bowl parts, but I failed to get his method to work for me. I’m pretty sure it would work for the spiked möbius you’ve created.)

Gorgeous and amazing again Bob but man you just gotta get some hot hide glue. These joints are, in your current weather, “just hold them for a few moments” joints. ...... and easy cleanup too!
PM me if I can help

Thanks for the nice comments. Spencer – it is more the congested space that restricts the clamping, will wait to see what you come up with. Pete – sure has been hot over here mate, had to put the Mexican hat on my profile picture.
